The line chart indicates the amount of water globally used by three major sectors over a century from 1900 to 2000, while the table shows the water consumed in two different countries in 2000.
During the entire period, Agriculture accounted for the largest amount of water consumption, whereas the least amount of water used was with households, and the figure in three sectors increased in a various degree. Moreover, Brazil was consumed more volume of water than its counterparts (DRC).
With regard to the first graph, in 1900, around 500 km3 of global water used by agriculture, from then onwards, it increased steadily to 1000 in 1950, and then rise more sharply to peak at around 3000 by 2000, whilst the volume of domestic use and industrial
Water scarcity is increasing worldwide and dramatically affecting first world nations such as Spain, Australia, and the United States. All nations are now starting to recognize that the world's water is a finite resource, and that resource is being drastically altered in both availability and quality by development, climate change and population growth. In the United States, the Colorado River is experiencing rapid declines in volume. Recent studies and data suggest that the changes in frequency, intensity, and timing of the availability of water will have substantial impact on the way we live our lives in the 21st century and beyond. As Letmathe Brakeck said, “I am confident that, under present
Water is one of the most precious resources, which support the life of almost everything in the world. Indeed, the world is covered by 75% water, but most of this water is not suitable for human consumption or use. On the same note, the world has been increasing its consumption of water due to the increasing population, leading to increased demands. The increased water consumption, which has been a result of high population, is worrying because the matter may lead to massive water shortages in the future.
Industries are expected to use 265 billow cubic meters of water per year (Doc. D). With that said, there is several industries that rely on water (Doc. D). At the same time, the need for water in agriculture decreases and the need for water in domestic issues gradually increases, while the need for water in industries frantically increases (Doc. C). The requirement of water in industries keeps climbing high year after year as the water supply drops. Moreover, many industries must-have a sizeable quantum of water, which drives the water crisis.
The study is intended to contribute to the national capacity building for water management. From the foregoing it can be seen that the study is important since it will contribute to the determination of ways of how water could be managed on a sustainable and efficient basis without incurring great negative externalities to the resource as well as to the environment.
The water supply now and in the future affects the population in many ways. According to “Water in 2050”, the water supply is the determining factor of how large the population may grow. In some areas lack of
Population, household size, and growth will influence all affect how on much water is used. We

In both Bolivia and Brazil locals rallied around a plethora of issues. Bolivia, specifically Cochabamba, rallied around the issue unfair water practices by the foreign company Bechtel. Cochabamba’s dependence on Bechtel sprung out of a need for water that had festered due to overpopulation, deforestation, and poverty. However, Bechtel proved to be a major problem and increased water rates by more than 50% which caused the locals to riot. Problems also exist in Brazil in the favelas and for the landless peasants. Favelas are small houses that are on land that is not owned by the occupants of the favela. People live in favelas due to extreme poverty as many favelas lack sewage, garbage collection, water and are plagued with drug dealing and crime.
“It is forecasted that agriculture will use the most water with about 400 billion cubic meters” (Document C). “Power uses the most water in the agriculture sector with 30%” (document D). In the future, it is forecasted that agriculture will still be using the most water and power is said to be using the most water. This problem helps explain China’s water shortage, so they can cut back on some water for power, and it also helps the government knows what is driving the water shortage and now that they know what the problem is they can find ways to solve it and cut back agriculture amount of
In North America and Europe which mainly consist of developed countries most of the water used in industry. In fact, about fifty percent of the water in each area consumed by industries. They consume about one third of total water for agriculture.
A combination of the two charts illustrates a variety of forms of water and the consumption of water for 3 different purposes in Egypt, Canada and Saudi Arabia.
Water scarcity is a problem that is currently affecting the entire world. Water is a crucial part of life and the importance of water for Brazil has a unique story. Brazil is a country that relies heavily on water for power and other essentials. However, the country has been facing obstacles in maintaining a positive water supply. One of the regions that are mostly impacted by this is the southeast region. The southeast region is where Sao Paulo, Rio de Janeiro, Minas Gerais and Espirito Santo are located. These states are the most populated states of the country. Sao Paulo is number one on that list with a population of 20 million people (Rigby, 2015).
Water is the fundamental asset to bolster all shape life on earth. Shockingly it is not equally disseminated over the world via season or area. All through the historical backdrop of the world dams and stores have been developed with a specific end goal to anticipate surges, to supply drinking and
According to water footprint studies, three classes of water use exists, namely, blue water which refers to the volume of surface and groundwater consumed in the manufacture of a product, green water which refers to the volume of consumption of rainwater excluding any runoffs and grey water is polluted water and by definition is the amount of freshwater needed to assimilate the load of pollutants given natural background concentrations and existing ambient water quality standards (Hoekstra et al 2011). The understanding of water footprint will eventually lead behavioral changes which will in turn ensure sustainable water use.
